Balancing personal interest and market demand is important when choosing a niche. If you pick something only because it's popular but you have no interest in it, staying motivated can become difficult. On the other hand, if you choose something you enjoy but nobody is searching for it or buying anything related, you may not see much success. A good way to balance both is to look at what you like and then check if people are actively searching for related products or information. If there’s enough interest and people are already spending money in that area, it could be a strong choice. Try to find where your interest meets actual demand. How do others handle this balance?
